At its most basic, thermal management—whether passive or active—is about putting controls in place to ensure that the cells of the battery operate within a narrow, optimal temperature window. EV batteries prefer to operate at or around the 70 °F (≈21 °C) mark making temperature extremes at both ends of the thermometer quite problematic.
Fireproof resin (as the basic matrix of the composite mixture) represents a viable solution for the use in the construction of electric vehicles (and its components) due to sustainable qualities such as: lightweighting, energy-efficient manufacturing, durability, stability, recycling and circularity.
Nomex® SafePakTM Flame Barrier offers up a cost-effective, easily customizable way to prevent the spread of thermal energy and/or flames up and into the passenger cabin of the vehicle. Nomex® SafePakTM can be laminated with pressure-sensitive adhesive for ease of application to the inside of the upper lid of the EV battery pack.
Results of experiments show significantly higher temperatures for the NCA battery and when comparing the three chemistries of the same size, the NMC batteries present the most reduced temperature rise, being regularly with 1 … 3 °C below the values of the LCO battery.
Cell-to-cell thermal protection involves the spaces between and around the individual battery cells. There are multiple performance materials—used either alone or laminated together into multi-functional material stacks—that can be used to achieve one or more thermal management objectives.
Nickel strips were used as electrical connections between the cells, accomplished using spot welding. The described battery module is presented in Fig. 8 a, while Fig. 8 b shows the module after being taken out from the mold where the composite material polymerized around the cells. Fig. 8.
